OSG CE And Submitter Testing And Monitoring

Line: 26 to 26
  A third round of tests, using multiple users, were performed in Summer 2009 (by Igor Sfiligoi):

    Submitted 5k jobs per user. Due to limited client resources (single CPU, 1G of memory) -maxidle 1k was used when using multiple DNs.
    With 4 parallel users the job rate limit is 21 jobs/min (compare this to 5.2 jobs/min using a single user).
    Can sustain 43 jobs/min if monitoring not important (compare this to 14 jobs/min using a single user).
    More details at: rates_gt2_r2_single_vs_multi_30min.ods or rates_gt2_r2_single_vs_multi_30min.pdf
  • Network latency is much more noticeable when a single DN is used. Using multiple users, the networking latencies don't seem to be a major issue.
